You can't see your deck card images.
You can't change the quantity of the cards in your deck.
If you tap any of the cards in your deck then they leave the deck.
There's no Lands.

There's no way to play your game. You should've taken the game down for maintenance during the update like more successful gaming companies. You know, test it yourselves before releasing it.... it's worth losing the couple hours of money than having to spend even more to fix all the errors.
